SVIP: Sequence VerIfication for Procedures in Videos. (arXiv:2112.06447v4 [cs.CV] UPDATED)

In this paper, we propose a novel sequence verification task that aims to
distinguish positive video pairs performing the same action sequence from
negative ones with step-level transformations but still conducting the same
task. Such a challenging task resides in an open-set setting without prior
action detection or segmentation that requires event-level or even frame-level
annotations. To that end, we carefully reorganize two publicly available
action-related datasets with step-procedure-task structure. To fully
investigate the effectiveness of any method, we collect …
